The present invention relates to a compactor device (10), comprising a compacting station (20) with an inlet port (20a) and an opposite outlet port (20b). This compacting station (20) further comprises motorisation means configured to cause the advancement and simultaneous crushing towards the outlet port (20b) of collapsible objects entering the inlet port (20a).The aforesaid compactor device (10) is characterised in that it comprises a blocking element (30) arranged at the outlet port (20b) and configured to hold collapsible objects inside the compacting station (20) when the blocking element (30) itself is in the closed position and to allow the aforesaid collapsible objects to leave the compacting station (20) when this blocking element (30) is in the open position. Furthermore, this blocking element (30) is configured to gradually and reversibly switch from the closed position to the open position when the collapsible objects push on the blocking element (30) from the inside to the outside of the compacting station (20).

Device (1, 100, 200) for pressing coffee powder (C) into a dosing filter (10), comprising: - a support structure (2), - a bearing frame (3) operatively associated with the support structure (2) and configured to carry the dosing filter (10); - pressing means (4) mounted on said support structure (2) on top of the bearing frame (3) and comprising a pressing body (41) configured to translate along a substantially vertical axis (X) between a rest position and at least a working position in which such pressing body (41) is configured to compress a dose of coffee powder (C) present in the dosing filter (10), wherein the pressing body (41) is configured to rotate about the axis (X) during said compression.

The present invention relates to a plant (10) for trimming and edging a metal laminar semi-finished product, comprising:- support means (20) configured to support and reversibly block the semi-finished product along a substantially horizontal support plane; these support means (20) are configured to rotate the semi-finished product around a machining axis (I) orthogonal to the support plane;- a first trimmer (30a) configured to cut the edge of the semi-finished product;- a first edge bander (30b) configured to bend the edge of the semi-finished product.It should be pointed out that the plant (10) still comprises:- a first tool holder (30) to which the first trimmer (30a) and the first edge bander (30b) are fixed with an angular misalignment substantially equal to 90° and along the support plane;- first rotation means (40) operatively connected to the first tool holder (30) and configured to rotate said first tool holder (30) around a first rotation axis (J) parallel to the machining axis (I);- first translation means (50) operatively connected to the first rotation means (40) and configured to reversibly translate the first rotation means (40) towards the support means (20).

A first treatment plant (100) and a second treatment plant (200) for respectively performing a first and a second surface treatment of a laminar support (1) for producing a multilayer laminar product (6).The first treatment plant (100) provides an outlet winding assembly (114) for winding on a transfer reel (400) the strip of laminar element (4) coupled with the treated laminar support (1), while the second treatment plant (200) comprises at the inlet an unwinding assembly (201) configured to unwind the transfer reel (400) of the first treatment plant (100) so as to perform a second treatment on said laminar support (1).

A method for producing a multilayer laminar product (6), comprising the operations of arranging a laminar support (1), covering a first face (1a) of the laminar support (1) with a first covering layer (2) in a polymeric resin and consolidating, at least partially, the first covering layer (2).The method further envisages pushing an embossed surface (107) against the first covering layer (2) with interposition of the laminar element (4) and causing the polymerization of the first covering layer (2).
